Data Binding Sluggish

[Graham]

Hello,

This afternoon, I have been working with Visual Studio 2010 and Telerik controls.

My windows 8.1 computer suddenly became rather unstable - this normally happens when there are Windows Updates to be applied.
So I rebooted the machine and allowed the updates to be installed.

Since doing this, Telerik control databinds have become INCREDIBLY slow. For example, the following code:

DateTime startDate = new DateTime(viewDateStart.Year, viewDateStart.Month, 1);
DateTime endDate = startDate.AddMonths(1);

while ((int)startDate.DayOfWeek != 1) startDate = startDate.AddDays(-1);        // 0 = sunday
while ((int)endDate.DayOfWeek != 0) endDate = endDate.AddDays(1);               // 0 = sunday

while (startDate <= endDate) {
       dayList.Add(startDate);
       startDate = startDate.AddDays(7);
}

rptCalendar.DataSource = dayList;
rptCalendar.DataBind();

At the point of the data bind, the dayList item only contains 5 records. It takes a good 5 to 10 seconds to step over the DataBind() statement.

Similarly, RadGrid is also taking inordinate amounts of time to DataBind(). The data in this instance comes from a Linq call, but this too is virtually instant.

It seems that a Windows update has somehow crippled Telerik control data binding.

Has anyone heard of this happening ?

Hello Graham,

This is strange, indeed. I don't recall coming across such a report. Can you please test your application with the latest version of the controls (dev or trial) to see whether this will change anything?

Eyup,

We purchased our copy of Telerik a couple of years ago and it is now out of support period.
If I download the latest version, is it going to revert my version to a demo or trial version ?
This is a production system and I can't afford for this to happen.

Hello Graham,

You will need to have an active license in order to use the dev version of the controls:
http://www.telerik.com/purchase.aspx

However, you can use some kind of back-up or test sample similar to your real project in order to temporarily try out the trial version of the Telerik controls.
